Practice the exact content PSI puts on your Oklahoma esthetics exam. Mapped to the official topic breakdown below — no guessing, no generic Milady-style filler.
Direct from the Oklahoma State Board of Cosmetology and Barbering and the PSI candidate bulletin.
Your SGS dashboard tracks your score in each of these categories so you know exactly where to study.
The tools students use every night in the 30 days before their test.
Oklahoma uses the PSI exam, which requires 75% or higher to pass. Practicing at least 10% above that on SGS mock exams is the sweet spot students who pass on the first try hit.
Oklahoma requires 600 training hours for esthetics, along with completing the PSI exam (written + practical). Minimum age is 16.
Every SGS practice question is mapped to the same topic categories PSI uses: Scientific Concepts (Infection Control, Anatomy, Chemistry); Skin Care and Services (Facials, Treatments, Hair Removal). Your progress dashboard shows which categories you're strong in and which need work before test day.

A common pitfall candidates fall into is underestimating the depth of knowledge required for the Infection Control section within Scientific Concepts. Because it's such a critical component of public safety in esthetics, the exam goes beyond basic definitions. Don't just learn what disinfection is; understand the different levels of decontamination, the specific types of disinfectants, and their appropriate uses for various tools and surfaces. Many candidates know the terms but struggle with application scenarios. My advice: think about every single tool and surface in a spa and what specific method you'd use to keep it clean and safe according to state regulations.
